That type of question is inappropriate. There are many problems caused by illegals that have nothing to do with taking jobs away from Americans. Sanctuary cities are using tax dollarts to house them (often in hotels), educate their kids, provide them with medical care (who do you think pays when an illegal woman shows up at the ER giving birth?), theft, human trafficking, drug trafficking, etc.
In Denver, there are about a dozen illegals with squeegees at every traffic light. When the cars stop for a red light, an illegal runs up and cleans the windshield. Then he goes to the driver's window and expects a handout. The car then drives to the next intersection. Another unwanted squeegee window cleaning. . . . . .
